The film is set in Canterbury-Bankstown and opens with the protagonist, Pauly (Paul Fenech), claiming that the following events are all true and that real names are used.

Pauly arrives late at work to find his employer, Bobo (Johnny Boxer), has hired a new delivery driver, Davo (Jason Davis).

Pauly explains to Davo that Bobo is crazy from being a forty-year-old virgin who lives with his mother, but is getting married the next day to a Vietnamese mail-order bride, Lin Chow Bang (Tuyen Le), who is sneaking into the country illegally.

Pauly then shows Davo the "Former Employee Hall of Shame", which features Sahib (Desan Padayachee), who was forced out for being too polite and not tough enough.

Sleek then details how he has another delivery driver, Habib (Tahir Bilgic) secretly film his sexual encounters without the women's knowledge.

[2] Louise Keller of Urban Cinefile said that the film's offensive humour was "very funny" and praised it for being irreverent, high-energy and over-the-top.

[3] The film was a source of controversy because of its use of vulgar humour, racial stereotypes and ethnic slurs (including choco, for non-white people).

[5] Therefore, Fat Pizza—among other films—marks a shift in the representation of minorities in Australian media away from sensitive, serious portrayals towards market driven entertainment (Khorana, 2019).

The favored reception of the film is argued to represent a large, youthful, ethnic-minority audience looking for an outlet against being minoritized in Australian media.

A crossover film between Fat Pizza and Housos – another television show created by Paul Fenech – was released on 27 November 2014.
